Abstract

A method for controlling access to a vehicle includes storing at a vehicle-based system a GPS location of the vehicle associated with the location at which the vehicle is parked. The vehicle-based system communicates with a mobile device to obtain a GPS location of the mobile device. The vehicle-based system blocks entry to the vehicle if the GPS location of the mobile device is outside a predetermined distance from the stored GPS location of the vehicle.

First claim

The invention claimed is:

1. A method for controlling access to a vehicle, comprising:
providing a vehicle-based system comprising a transceiver operatively connected with a vehicle control module; and
providing a mobile device having a GPS module and a wireless communication module;
storing at the vehicle-based system a GPS location of the vehicle associated with the location at which the vehicle is parked;
communicating via the vehicle-based system with the mobile device via the transceiver and the wireless communication module to obtain a GPS location of the mobile device; and
blocking via the vehicle-based system entry to the vehicle if the GPS location of the mobile device is outside a predetermined distance from the stored GPS location of the vehicle.

2. The method recited in claim 1 , comprising the following further steps:
sending instructions to the mobile device via the transceiver and the wireless communication module requesting the GPS location of the mobile device,
determining the GPS location of the mobile device using the GPS module, and
transmitting the GPS location of the mobile device to the vehicle control module via the wireless communication module and the transceiver.

3. The method recited in claim 1 , comprising the step of determining via the vehicle-based system when the vehicle is parked.

4. The method recited in claim 1 , comprising the following further steps:
verifying whether the mobile device is authenticated with the vehicle control module, and
blocking entry to the vehicle if the mobile device is not authenticated with the vehicle control module.

5. The method recited in claim 1 , comprising the following further steps:
receiving an entry request by the vehicle control module;
allowing entry to the vehicle if at least the GPS location of the mobile device is within a predetermined distance from the stored GPS location of the vehicle.

6. The method recited in claim 5 , wherein the communication to obtain the GPS location of the mobile device is initiated upon the entry request.

7. The method recited in claim 5 , comprising the following further steps:
the vehicle based system having a base station in the vehicle configured to generate an electromagnetic field having a first frequency and having a receiver to receive transmissions having a second frequency,
providing a security token having a receiver for the electromagnetic field having the first frequency and a transmitter for transmissions having the second frequency;
generating the electromagnetic field having the first frequency by the base station and receiving the electromagnetic field by the security token;
transmitting a message by the security token to the vehicle based system via the transmitter of the security token and the receiver of the vehicle based system;
verifying the message via the vehicle control module; and
allowing entry to the vehicle if at least the verification was successful and the GPS location of the mobile device is within a predetermined distance from the stored GPS location of the vehicle.

8. The method recited in claim 7 , wherein the security token is a key fob.

9. The method recited in claim 7 , wherein the first frequency is lower than the second frequency.

10. The method recited in claim 9 , wherein the first frequency is a low-frequency and the second frequency is a radio-frequency.

11. The method recited in claim 7 , wherein the receiver of the security token is a RFID-receiver or a RFID-transponder.

12. The method recited in claim 7 , wherein the entry request is generated when using a door handle of the vehicle or when a proximity sensor detects the proximity of a person at a door of the vehicle.

13. The method recited in claim 5 , wherein the determination if the GPS location of the mobile device is outside the predetermined distance from the stored GPS location of the vehicle is made after receiving the entry request by the vehicle control module.

14. A system for controlling access to a vehicle, comprising:
a vehicle-based system comprising a transceiver operatively connected with a vehicle control module and a mobile device,
wherein the mobile device and the vehicle-based system are configured to jointly perform a method for controlling access to a vehicle, the method comprising:
providing a vehicle-based system comprising a transceiver operatively connected with a vehicle control module; and
providing a mobile device having a GPS module and a wireless communication module;
storing at the vehicle-based system a GPS location of the vehicle associated with the location at which the vehicle is parked;
communicating via the vehicle-based system with the mobile device via the transceiver and the wireless communication module to obtain a GPS location of the mobile device; and
blocking via the vehicle-based system entry to the vehicle if the GPS location of the mobile device is outside a predetermined distance from the stored GPS location of the vehicle.

15. The system recited in claim 14 , wherein the system is a vehicle keyless entry system.

16. The system recited in claim 14 , wherein the system comprises a security token.

17. The system recited in claim 14 , wherein the mobile device and the vehicle-based system are configured to make the determination if the GPS location of the mobile device is outside the predetermined distance from the stored GPS location of the vehicle is made after receiving the entry request by the vehicle control module.
